First data on long-legged flies (Diptera, Dolichopodidae) of the Onezhskoye Pomorye National Park (Arkhangelsk Region, Russia)

Abstract

The fauna of Dolichopodidae in the Arkhangelsk Region was studied sporadically and currently in-cludes 50 species. Onezhskoye Pomorye National Park (Arkhangelsk Region, Russia) was established in 2013 to protect the pristine forests and coastal ecosystems of the hardly accessible territories along the White Sea coast of the Onega Peninsula. The insect fauna of the National Park was almost un-known until recently, with only 17 Diptera species from the Culicidae and Chironomidae families listed in the online cadaster. During the short expedition to Onezhskoye Pomorye National Park in July–August 2020, more than 350 Dolichopodidae specimens were collected with yellow pan traps and sweep netting on routes that mainly passed through coastal habitats. Nineteen species of Dolichopodi-dae have been reported for the first time from this territory. Thirteen species are reported for the first time from the Arkhangelsk region, bringing the total number of known species to 63. The species list is given and supplied with brief comments on habitat and distribution. Photos of some typical habitats are provided. Most of the discovered species are widespread throughout the Palaearctic Region. Rarer species include Dolichopus diadema, which probably represents a southern Palaearctic element, and Hydrophorus norvegicus, which was previously known only from Fennoscandia.
